|March 2008||Zero-Inflated Poisson and Zero-Inflated Negative Binomial Models Using the COUNTREG Procedure (PDF)
This paper studies the performance of different count models on a simulated example. The results demonstrate that among the count models we consider, in many cases a Poisson model tends to be overly restrictive.
|March 2008||Using SAS/OR to Improve Emergency Response Times with Better Ambulance
Using the new SAS/OR procedures, SAS software and the San Francisco Fire Department analyzed emergency response operations to optimize ambulance locations and relate that information into dispatch procedures to decrease response times. This paper discusses the formulation of the problem, solution, and practical challenges to implementation.
